I feel your pain.
The short answer is: you can’t do what you want. There’s no hidden toggle, no JSON hack, no plugin, and no amount of wishful thinking that will make Bambu Studio behave like modern software. They locked the UI down, and you’re running head-first into those limits.
Two things seem to be working against you:
- It looks like you’re on a low-resolution or physically small display. Laptop perhaps?
- It also looks like your Windows is scaled to 125% or higher, a common practice on smaller displays.
Those two conditions turn Bambu Studio into a wall of oversized menus. That’s not your fault. That’s what happens when a company decides that UI flexibility isn’t a priority and forces everyone into the same rigid layout.
If you’re on a 13" laptop with common 1920x1080 resolution, the math is unforgiving. Bigger scaling = giant menus. Smaller scaling = squinting at ant-sized text. Bambu gives you no middle ground.
Workaround #1 – Windows per-app DPI override
This is the only real lever you can pull from outside the software.
Right-click the Bambu Studio icon in your taskbar → Properties
- Go to the Compatibility tab
- Click “Change High DPI Settings”
- Enable “High DPI scaling override”
- Experiment with Application, System, or System Enhanced
You might need to log out and back in for the changes to take effect. A full reboot sometimes helps. The internal platform that Bambu uses behaves inconsistently depending on your GPU drivers, so your mileage will vary and you may need to experiment with other settings like Program DPI located at the top of the menu.
This won’t magically fix the UI, but it may shrink the menus enough to make the workspace usable.
Orca Slicer to the rescue… maybe
If your firmware is past 1.8 on the P1 or X1, skip this section. Bambu Labs deliberately shut off the path that allowed Orca to control their printers. If you didn’t update, you still have options. If you did, you’re locked into the walled garden.
Before the lockout, Orca offered two quality-of-life features that Bambu chose not to bring forward into their own fork, or at least from versions prior to BS 1.9.
- Shrinkable toolbars
- Tear-away and dockable panels
These don’t solve the oversized-menu problem entirely, but they give you back precious screen real estate and make small displays far more tolerable.

And yes, the irony is obvious: the community-built fork had the better UI, and Bambu Studio never bothered to reintroduce those improvements even after borrowing from Orca’s codebase years ago.
Bottom line
You’re not doing anything wrong. You hit a limitation Bambu built into the software. Until they decide to let users detach panels, resize toolbars, or customize their workspace like every serious visual (CAD, Graphics etc) tool on Earth, you’re stuck with workarounds instead of solutions.
